My first question is about the lesson below.
I was wonder about" わたしは さおりと いい ます". Is " と いい ます" informal way of saying" わたし はさおりです".
My second question is about the usage of watashi in hiragana and kanji in the lesson below.
わたし 私
Is it optional to the person to use the hiragana or kanji version of the word.
